Since the year 2000, scientific reports that provide evidence of climate change have grown in number.

Scientists now are much more certain that:

1. Global climate is rapidly changing
2. Human activity is the main cause
3. The effects will intensify this century

More importantly, scientists consider it essential that we act now to reduce greenhouse gas emissions, before major and rapid changes to our climate cause irreparable and irreversible harm to the environment and overwhelm our economy.

The phrase “global warming” is not entirely accurate. The term “climate change” is far more descriptive. Scientists do predict that the earth’s average temperature is going to increase.  However, the most noticeable effect of climate change will be that the weather will become more variable, with a much greater frequency of extreme events such as hurricanes and droughts.

Evidence of climate change:

1. 1998 was the hottest year on record, followed by 2002, 2003, and 2004
2. The ten hottest years on record have all occurred since 1990
3. According to the most recent United Nations report, without a concerted mitigation effort, the average global surface temperature in the year 2100 will likely be 2.5 to 10.8 degrees Fahrenheit higher than in 1990
